NGC 4526 (also listed as NGC 4560) is a lenticular galaxy with an embedded dusty disc, located approximately 55 million light-years from the Solar System[3] in the Virgo constellation and discovered on 13 April 1784 by William Herschel.[6] Herschel observed it again on 28 December 1785, resulting in the galaxy being entered twice into the New General Catalogue.[6]

The galaxy is seen nearly edge-on. The morphological classification is SAB(s)0°,[5] which indicates a lenticular structure with a weak bar across the center and pure spiral arms without a ring.[7] It belongs to the Virgo cluster and is one of the brightest known lenticular galaxies.[5] In the galaxy's outer halo, globular cluster orbital velocities[8] indicate abnormal poverty of dark matter: only 43±18% of the mass within 5 effective radii.

The inner nucleus of this galaxy displays a rise in stellar orbital motion that indicates the presence of a central dark mass. The best fit model for the motion of molecular gas in the core region suggests there is a supermassive black hole with about 4.5+4.2
−3.0×108 (450 million) times the mass of the Sun.[9] This is the first object to have its black-hole mass estimated by measuring the rotation of gas molecules around its centre with an astronomical interferometer (in this case the Combined Array for Research in Millimeter-wave Astronomy).
